Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Early Treatment | Infants randomized to the early treatment group will receive pharmacologic treatment of the PDA to produce PDA closure. Within 24-36 hr following the last treatment dose an echocardiogram will be obtained to document the degree of ductus closure or patency.~Echocardiograms will be obtained at 1) 10-14 days after study entry (if the PDA was open and of moderate size on the last echocardiogram), and 2) at the time of hospital discharge (if the PDA was open (any size) on the last echocardiogram). The echocardiogram obtained at discharge will be used to determine the need for outpatient follow-up.~pharmacologic treatment of the PDA: Following randomization, infants will be treated with medications used to produce PDA closure. | 36 | 104 | OG000 |
| Group 2 | Conservative Treatment | Infants randomized to the Conservative Treatment approach will receive no pharmacologic treatment of the PDA but will be followed to determine if they meet criteria for later PDA rescue treatment (Infants will be eligible for rescue treatment of their persistent PDA if they meet the rescue treatment criteria.)~Echocardiograms will be obtained at 1) 10-14 days after study entry (if the PDA was open and of moderate size on the last echocardiogram), and 2) at the time of hospital discharge (if the PDA was open (any size) on the last echocardiogram). The echocardiogram obtained at discharge will be used to determine the need for outpatient follow-up.~no pharmacologic treatment of the PDA: Following randomization, infants will NOT be treated with medications used to produce PDA closure (unless they develop rescue criteria at a later point in time). | 45 | 98 | OG001 |
